Gas burner assembly

ABSTRACT

A gas burner includes a burner seat having therein a path for provision of gas, a burner core rested on an inner periphery defining the path and having multiple slits defined through opposite sides of the burner core and a burner cap placed on top of the burner seat to sandwich the burner core. The slits are defined in such a manner that an air flow inside the burner core is rotated and directed upward relative to the burner core.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a gas burner assembly, and more particularly to a gas burner assembly having a burner core sandwiched by a burner seat and a burner cap and having slits defined through opposite sides of the burner core, wherein each of the slits is deviated from and inclined relative to the radius of the burner core such that an eddy effect occurs when the gas burner is in use.

2. Description of the Prior Art

Nowadays, the gas burner available on the market has slits defined in the burner core and communicating with a gas path defined in the burner seat. All of the slits are defined in a manner such that when gas is filled in the path and the gas burner is lit, the fire is substantially vertical to the gas burner. Therefore, when a pot is placed on top of the gas burner, the pot is evenly heated. As a result of this kind of slit design, it requires a pretty long period of time until the pot reaches the predetermined temperature. Also, the gas volume used to heat up the pot is wasted due to the bad design of the conventional gas burner.

To overcome the shortcomings, the present invention tends to provide an improved gas burner assembly to mitigate the aforementioned problems.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide an improved gas burner assembly to effectively consume gas and to shorten heating time period.

In order to accomplish the objective, the gas burner assembly of the present invention includes a burner seat, a burner core and a burner cap sandwiching the burner core with the burner seat. The burner core has slits defined through opposite sides of the burner core and each slit is deviated to and inclined relative to the radius of the burner core such that when the gas burner assembly is in use after gas is filled in a path defined in the burner seat, fire is directed to a direction and an eddy effect is generated inside the gas burner assembly of the present invention. Due to the eddy effect, the heating area is concentrated in the center of the gas burner assembly. Thus temperature rising is fast and gas consumed during the heating period is little.

In yet another objective of the present invention, each slit is deviated from the radius for 30 degrees.

A further objective of the present invention is that each slit is inclined relative to the radius for 25 degrees.

Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIGS. 1 and 2, it is noted that the gas burner assembly in accordance with the present invention includes a burner seat (10), a burner core (20) and a burner cap (30).

The burner seat (10) has a path (11) defined therein and communicating with a gas source (not shown).

The burner core (20) has a circular shape and multiple slits (21) defined through opposite sides of the burner core (20). The burner cap (30) is provided with a cap portion (31) and a skirt portion (32) extending downward from a bottom face of the cap portion (31).

With reference to FIG. 3, it is noted that when the gas burner assembly of the present invention is in assembly, the burner core (20) is placed and rested on a top face of an inner periphery defining the path (11) of the burner seat (10). Then the burner cap (30) is placed on top of the burner seat (10) as well as the burner core (20) to allow the skirt portion (32) to engage with a top face of an outer periphery defining the path (11) and the cap portion (31) to engage with a top periphery of the burner core (20). It is noted that after the assembly of the gas burner assembly of the present invention is finished, the path (11), an inner periphery of the skirt portion (32) of the burner cap (30) and an outer periphery of the burner core (20) form a space (A) in which gas flows. Still, because the slits (21) are defined through opposite sides of the burner core (20), the slits (21) communicate with the space (A) defined by the inner periphery of the skirt portion (32) of the burner cap (30) and the outer periphery of the burner core (20).

Therefore, when the gas source starts supplying gas to the path (11) of the burner seat (10), the space (A) communicating with the path (11) is also filled with the gas, which allows the gas to flow to the slits (21). The description above concerning the structural relationship among components is substantially the same as that of the conventional gas burner. However, due to the design of the slits (21), the gas burner assembly of the present invention is able to present much better efficiency than the conventional gas burner.

With reference to FIGS. 4 and 5, it is noted that the top plan view of the burner core (20) shows that each slit (21) is defined in such a manner that a 30-degree deviation from a radius of the burner core (20) exists. Also, each slit (21) is inclined upward from the radius of the burner core (20) for 25 degrees. From the accompanying drawings, each slit (21) is deviated in such a manner that the gas is directed to a direction where an eddy flow is generated inside the gas burner assembly of the present invention.

When an eddy flow is generated inside the gas burner assembly of the present invention, the fire as a result of the gas provision is concentrated to a center of the burner core (20). Furthermore, due to the upward inclination of the slits (21), the fire is further concentrated in the center of the burner core (20). As a result, a pot placed on top of the gas burner assembly of the present invention is heated rapidly. Thus the volume of gas consumption is little, yet the heating duration is reduced.

With reference to particularly FIG. 4, it is noted that a counterclockwise gas flow in generated inside the burner core (20) due to the arrangement of the slits (21). Thus when the gas inside the gas burner assembly is lit, the fire is directed to, by the gas flow, have a counterclockwise direction. In addition to the counterclockwise direction of the fire as a result of the 30-degree deviation of the slits (21) to the radius of the burner core (20), the 25-degree inclination of the slits (21) concentrates the fire to the center of the burner core (20).

It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
